switch is established by a Telnet/SSH connection.  
2. Each command mode has its own set of specific commands. To configure some commands,  
you should access the corresponding command mode firstly.  
Global Configuration Mode: In this mode, global commands are provided, such as the  
Spanning Tree, Schedule Mode and so on.  
Interface Configuration Mode: In this mode, users can configure one or several ports,  
different ports corresponds to different commands  
a). Interface gigabitEthernet: Configure parameters for an Ethernet port, such as  
Duplex-mode, flow control status.  
b). Interface range gigabitEthernet: Configure parameters for several Ethernet ports.

c). Interface link-aggregation: Configure parameters for a link-aggregation, such as  
broadcast storm.  
d). Interface range link-aggregation: Configure parameters for multi-trunks.  
e). Interface vlan: Configure parameters for the vlan-port.  
VLAN Configuration Mode: In this mode, users can create a VLAN and add a specified  
port to the VLAN.  
3. Some commands are global, that means they can be performed in all modes:  
show: display all information of switch, for example: statistic information, port information,  
VLAN information.  
history: Display the commands history.  
1.3 Security Levels  
This switch’s security is divided into two levels: User level and Admin level.  
User level only allows users to do some simple operations in User EXEC Mode; Admin level  
allows you to monitor, configure and manage the switch in Privileged EXEC Mode, Global  
Configuration Mode, Interface Configuration Mode and VLAN Configuration Mode.  
Users get the privilege to the User level once logging in by Telnet/SSH. However, Guest users are  
restricted to access the CLI.  
Users can enter Privileged EXEC mode from User EXEC mode by using the enable command. In  
default case, no password is needed. In Global Configuration Mode, you can configure password  
for Admin level by enable password command. Once password is configured, you are required to  
enter it to access Privileged EXEC mode.  
1.4 Conventions  
1.4.1 Format Conventions  
The following conventions are used in this Guide:  
Items in square brackets [ ] are optional  
Items in braces { } are required  
Alternative items are grouped in braces and separated by vertical bars. For example: speed  
{10 | 100 | 1000 }

the sum of bandwidth of its member port.  
LACP (Link Aggregation Control Protocol) is defined in IEEE802.3ad and enables the dynamic link  
aggregation and disaggregation by exchanging LACP packets with its partner. The switch can  
dynamically group similarly configured ports into a single logical link, which will highly extend the  
bandwidth and flexibly balance the load.

Description  
The mac address-table max-mac-count command is used to configure the  
Port Security. To return to the default configurations, please use no mac  
address-table max-mac-count command. Port Security is to protect the switch  
from the malicious MAC address attack by limiting the maximum number of the  
MAC addresses that can be learned on the port. The port with Port Security  
feature enabled will learned the MAC address dynamically. When the learned  
MAC address number reaches the maximum, the port will stop learning.  
Therefore, the other devices with the MAC address unlearned can not access to  
the network via this port.  
Syntax  
mac address-table max-mac-count {[ max-number num ] [ mode { dynamic |  
static | permanent }] [ status { disable | enable }]}  
no mac address-table max-mac-count  
Parameter  
num —— The maximum number of MAC addresses that can be learned on the  
port. It ranges from 0 to 64. By default this value is 64.  
dynamic | static | permanent —— Learn mode for MAC addresses. There are  
three modes, including Dynamic mode, Static mode and Permanent mode.  
When Dynamic mode is selected, the learned MAC address will be deleted  
automatically after the aging time. When Static mode is selected, the learned  
MAC address will be out of the influence of the aging time and can only be  
deleted manually. The learned entries will be cleared after the switch is rebooted.  
When permanent mode is selected, the learned MAC address will be out of the  
influence of the aging time and can only be deleted manually too. However, the  
learned entries will be saved even the switch is rebooted.  
status —— Enable or disable the Port Security function for a specified port. By  
default, this function is disabled.

Download from Www.Somanuals.com. All Manuals Search And Download.  
 
sp —— Strict-Priority Mode. In this mode, the queue with higher priority will  
occupy the whole bandwidth. Packets in the queue with lower priority are sent  
only when the queue with higher priority is empty.  
wrr —— Weight Round Robin Mode. In this mode, packets in all the queues are  
sent in order based on the weight value for each queue. The weight value ratio  
of TC0, TC1, TC2 and TC3 is 1:2:4:8.  
sp+wrr —— Strict-Priority + Weight Round Robin Mode. In this mode, the switch  
provides two scheduling groups, SP group and WRR group. Queues in SP  
group and WRR group are scheduled strictly based on Strict-Priority mode while  
the queues inside WRR group follow the WRR mode. In SP + WRR mode, TC3  
is the SP group; TC0, TC1 and TC2 belong to the WRR group and the weight  
value ratio of TC0, TC1 and TC2 is 1:2:4. In this way, when scheduling queues,  
the switch allows TC3 to occupy the whole bandwidth following the SP mode  
and the TC0, TC1 and TC2 in the WRR group will take up the bandwidth  
according to their ratio 1:2:4.  
equ —— Equal-Mode. In this mode, all the queues occupy the bandwidth  
equally. The weight value ratio of all the queues is 1:1:1:1.
